Hydrogen Ion + 2 Pyruvic acid → (S)-2-Acetolactate + Carbon dioxide
(S)-2-Acetolactate + Hydrogen Ion + NADPH → (R)-2,3-Dihydroxy-isovalerate + NADP
Isovaleric acid + L-Glutamic acid → L-Valine + Oxoglutaric acid
(R)-2,3-Dihydroxy-isovalerate → Isovaleric acid + Water
Proton-translocating NADH-quinone oxidoreductase
